Radon Mitigation >> Crawlspace Drying

Some homes have more than one type of foundation design. For example, it is very common to have both a basement under part of the house and then to have a slab-on-grade or crawl space under the other part of the house. In these circumstances a mixture of Crawlspace Drying reduction methods might be required to minimize radon gases to below 4 pCi/l. There could be several techniques that a radon mitigation contractor could use to lower radon gases in your house.

  1. Some methods would prevent Crawlspace Drying from coming into your house while others minimize radon gases after it has gotten in. Experts normally suggest techniques that block the access of radon. In most cases, easy systems using underground tubing and a radon system fan might be used to minimize radon. Such systems are called active soil depressurization, and do not need major alterations to your house. These simple systems eliminate Crawlspace Drying gas from below the surface of the concrete floor, or a casing in a crawl space, and the foundation before it could come into the house. Radon mitigation experts use other techniques that might also work in your house.
  2. The right system differs on the layout of your home and other issues. Any knowledge that you might have about the foundation construction of your house could help your radon mitigation expert select the best system. Your radon mitigation professional will use a visual examination of your home and plan a system that is appropriate. If this examination fails to offer enough material, the professional will require to perform diagnostic exams to help plan the best Crawlspace Drying lessening system for your house. Whether diagnostic exams are required is based on details particular to your home, like the foundation design, what type of construction material is under your home.
  3. And by the radon mitigation professional’s experience with similar homes and similar radon test's findings. In homes that have a basement or a slab-on-grade foundation, radon gas is typically minimized by one of four kinds of active soil depressurization: sub-slab depressurization, drain tile depressurization, sump hole depressurization, or block wall depressurization. Sub-slab depressurization is the most widely used and normally the best technique for minimizing Crawlspace Drying. In this particular system, one or more suction tubes pass into the slab into the crushed rock or soil underneath.
  4. The tubes also might be put below the concrete floor from outside the house. A radon gas vent fan attached to the suction tube draws the radon gas from under the home and releases it into the atmosphere. If your house is constructed with a crawlspace, the radon mitigation technique will differ on the kind of slab, how easily accessible it is, and whether or not the area is large enough to work in. If your crawlspace has a concrete slab, the ideal Crawlspace Drying mitigation method is sub-slab suction. If it has an dirt floor, the ideal mitigation method is sub-membrane suction. With sub-membrane depressurization, the slab is covered with a thick piece of plastic sheet sealed to the crawlspace exterior walls, foundation piers and any openings of the membrane.
